SYNOPSISThis paper refers to 13 children who were found to have glycosuria on routine testing of urine, but who had no symptoms referable to diabetes. Each child had one or more abnormal glucose tolerance tests on initial testing, but further observations revealed continuing glucose in only 1 child, and normal glucose tolerate in all those retested.The significance of abnormal glucose tolerance ni children without symptoms referabale to diabetes, is discussed. Treatment appropriate to diabetes mellitus is not recommended in the absence of clinical symptoms and with only the evidence of one abnormal glucose tolerance test. Further observations during succeeding months should first be made.
